will it be possible to make these watercooled with c1 s3 s5 waterblocks?
thanks for anyone thaking the time to explore or anwser.
The cost would make it something not really great for ROI. With 6 blades you need 3 blocks. Also you would need housing to put them in. I'm not really a fan of syscooling but if you were to do it you chances are better off with S5 kit and regular s5's. Unless you are really good at modding and looking for a project. But I highly suggest sticking with fan's in most cases. Just chances of ROI go down when you start to add lots of water cooling gear to it. Also when it comes to resell it might take a special buyer that want's the water cooling. |

Even if you have free electricity ROI is hard to reach if you spend money for miners
In 4 years with free electricity, one still may not make their money back? I'm personally not a miner, and I understand it's too late in the game for the general population to get involved... but that sounds ridiculous. With free electricity, OP still shouldn't expect to turn a profit? Some are pretty anti-mining. Best way to calculate ROI is something like this - https://bitcoinwisdom.com/bitcoin/calculatorOP add up all costs including if you have VAT, etc. That will help you see how long a miner would take to pay off. Also when you say 4 years are you talking about some kinda student housing where you just have one room? |

My electricity price is 0. But I don't know how much I can pull from my wall plugs.
You need to tell us a little more. Are you saying it is one room that you are in? (This makes a huge difference as as heat and sound). Do you just have one room, multiple rooms? Do you circuit breaker you have access to? |

Hey Bitmain can you please check your automatic reply system. You have now send me 10 email confirming the open of my ticket.  yeah my order has not confirmed even though I sent a payment... It does not confirm instantly. It take 4 (i think either that or 3) conformations for it to confirm. If it does not do that in a hour it shows unpaid. But you can email and after holiday they will fix it. Has it been a hour since you paid? If less then hour your waiting on those confirmations. 84 confirmations already...I sent them 3 x emails but no reply. I don't know if it is because I sent 0.002 btc MORE than was needed by accident?!? Anyway now it says my order is void but I hope it sorted after the holiday... They will fix it after holiday. If it goes void they have to fix it manually it seems they don't automate the process. But once holiday is over give them a email. They likely will have a backlog from holiday so might take a bit longer then normal. But try to include order number, paid to address, paid from, transaction, link to transaction, etc. I put all possible information they might need in email and it seems to work. But it is a pain if it does not get confirmed status. |

Without even thinking about it...
7000gh = 7th @ 3500w = 0.5w per gh...
It doesn't even matter what price this is unless its free & u have free electricity
This machine is not worth any money when the S7 is 0.25w per gh...
Buy 2 and have 10th @ 0.25w & kill the spoondoolies machine..
Here is what they have announced SP50 - http://www.spondoolies-tech.com/products/sp50The did skip SP40 so there are hopes of a hobby miner to come, but no one can say if it will happen or not. If it does though it likely will be around 0.15W/GH/s like the SP50. So a decent amount below the .25 even. |

Crazy I would never of guessed those dev kits might be a money maker. Don't remember price but it was not cheap. I'm thinking chip by itself was pretty high so I doubt ton's of devs have it. I still cant wrap my mind around a company getting a chip made, a miner made, then going silent. Does not make sense. they are either 1) mining them selves or thru partnerships with other china scrypt farms or 2) mining themselves and also selling chips in bulk in china for other data halls but yeah.... LTC difficulty is going up after halving....so there is 'new' stealth equip/chips out there someplace imho ......... we will be the last to know  I feel the same. It goes from hey we have by a good amount the best chip for LTC around! Here are some fun giveaways... to nothing not a word about sales. And sales are important to stay alive as a company. I think 1 or 2 is very likely. And also likely they wish they never would have announced as they choose an option besides going to hobby customers. |

The S7 is FAR less power efficient than the SP50. There is an enormous difference between 0.25 and 0.15 w/gh. Unless there is competition in the market (which at the moment, there isn't), it is really not a good idea to buy the S7, as bitmain has no incentive to lower their prices to realistic levels, and their miner has already been eclipsed. Even at this very optimistic $0.05/kwh, we're looking at 365 days until breaking even on S7s, not factoring in: - The block reward halving.
- Significant hardware lead time. (best case, they'll be hashing 3-4 weeks from today)
- More efficient hardware being released over the next year which spikes difficulty.
- Cost of PSUs.
- Downtime from damaged miners (as they await RMA), power loss, and internet blackouts.
As for difficulty, the simulation assumes that the rate of difficulty increase stays the same (8.72% per month). That's a very optimistic difficulty estimate, since SP50s haven't even been deployed in large qtys yet. Sim link: https://coinplorer.com/Hardware/Simulate/56108b61226bf41570cbce49?key=079d11b5-c797-4d29-8f91-61bd6fce8addEven in the best case, almost fairy-tale like scenario outlined above, our numbers are shit. I am not comfortable in organizing a hardware buy that is doomed by math. Now, as for the strategy of selling the S7s early and buying SP50's: It's fairly complicated to do that. We'd need to find a buyer/multiple buyers for the s7s, pay escrow fees, hold the funds, negotiate with Spondoolies, and then purchase the SP50s. It exposes us to more risks: What if we can't find a buyer, or we can't negotiate a favourable deal with Spondoolies after selling the miners? Plus, we still have the problem that we greatly overpaid for our miners, and we are counting on suckers to overpay for ours. We are in no rush, absolutely no rush at all, to get this done. What we need is competition, price quotes from the competition, and the math to add up. Right now, we have none of those. I am for finding that electricity price of .05 or less the very optimistic price, and not easy to get. A S7 on .05 electricity costs less then a SP50 on .10 electricity. This is why I think finding cheap electricity is so important. On SP50 we really don't know much yet. We have a picture and stats. We really have no idea on the release date. And even once it launches I think it will take multiple to get it at first at least. So were talking a lot of money. I could be wrong I just think S7 and SP50 are geared for different customers. And I could be wrong I'm just speculating. I like this idea a lot just think it needs a little tweaking and some things decided eventually. |

If you have a little extra money look at local community college, trade school, college, university etc. I really benefited with the option of being able to have a teacher on learning coding.
Some of the options above are higher then others. But if you have a local community college likely you can get a programming class for not a huge amount of money. (yes much higher then just a book though).
And if you don't have any money or don't want to spend money, consider finding a student in that field to teach you in their spare time, or take them out for coffee to just talk about it. There's probably coding clubs or groups of people that just love to talk about it in your area of the world. This is actually a really awsome idea. I forgot all about the group studies and one on one tutoring. If you contact the book store on campus most likely you can get a used copy of programming in certain languages. Depending on college/university size they may have one or multiple types. If you offer a decent wage for a good student that has passed the class you could get one on one tutoring for far cheaper then any class. You would do learn at home and hit any problems bring it to tutor maybe once a week. If you have the money you will find the class very beneficial though. |

to follow up on max memberships
depending if ck can give a clean summary maybe we do 2 of 15.
keeping track right now is mechanical check on my part.
plus TheRealSteve and encad have some background tracking software in place
If we do 2 poolclubs
1 with 15 members and the second with 15 members each one is separate. you could get.
1/15 share of 7.5 coins and the other 17.5 coins could be given split via shares.
So a guy with 1 stick would get 0.5btc and a very tiny piece of the 17.5 coins
A guy with 100 sticks would get 0.5 btc and a bigger piece of the 17.5 coins
Still makes an incentive for a 1 stick miner. And really helps bigger miners more then our current setup.
I know that going over 30 or 35 dilutes too much. So long term I would think 2 clubs. and a mixed reward system may be better.
Each being separate would kinda suck if one hit it and was not yours. So if you have multiple sticks will you be able to be part of multiple clubs? Point 1 stick twords group and 1 to 2nd group, etc? |

All politicians are a bunch of stealing fuckers!
Domestic is ~.17$/kw but you have options like half the price in the night, or 1MW at ~.13$/kw.
Or friends with small business that have ~.05$/kw
99% of the time i go for used miners from Europe, because i don't have the $ for new equipment and the tax is taken care by the first owner
All politicians are not to the 1/4th level on vat. That .13-.17 pretty much means you will not ROI. The .05 it is possible but like you said any new gear is going to have vat and kill ROI. I think you are better off with paying a hosting center. As a miner I understand that really sucks. But some places just are not really mineable. |

Its currently holiday in china so I guess this is why we dont have any answer from bitmain. It will be very hit and miss until holiday is over. The majority of workforce will not be there until it's over. When they warn about a holiday they really do mean taking it off. After they get back it looks like they have quite a bit of things to do. I suspect a backlog of items for a bit. |

Hello all a little of topic?
Hey @J4bberwock how is the progress on the replacement board for the old gridseed orbs.
Thanks.
I think a big thing would be if SFards is making and shipping chips. I don't think with the silence chips will be sold at this point to general public. There are the lucky ones who ordered them early on with dev kits and such. That is a good question anyone that was working on a project have you tried to buy chips from SFards in any quantity lately? |

24% in Romania!
Does no one complain to the Romanian government? I might be spoiled in us but people would be complaining to most levels of government if there was a 1/4 the price vat. Honestly even if you like hardware it would be hard to justify buying a miner at 24 percent vat. Pretty much your only option is if you find hosting somewhere with much less vat to pay to host your machine. Out of curiosity what is your electricity price in Romania? |

Ok so I ordered some new mining hardware, and when it comes in and is all set up is should be slightly over the 10TH/s mark. I plan on pool mining, but my question is; at this point is it enough to solo mine? Would I have a good chance at finding any blocks? Just for example purposes what would I possibly be able to find in a period of 1 month?
What hardware did you order and what is your electricity price? That is some of the important information. And chances of hitting a block with 10T are not great at all. You will most likely be doing pool mining which most miners do at this point. Solo mining with 10T I still would consider "lotto mining". Basically high rewards but chances are very low. |

I'm thinking you guys could really do with share summaries being recorded/added somewhere to solo pool. I may do that to encourage these sort of clubs in the future.
Hopefully it is not that difficult. I think it would be beneficial If you have the time to do it. It would be very much appreciated. I realize we are not a 100 T group. But I think we are a long term club. So I understand if not on top of to-do's. But support of clubs like this would be amazing if you have time for even just a summery page. |

The problem remains though if you have an infected computer and access a CD or USB it can get the information from when you access it, with a security breach. So even though a CD cannot be written to again (assuming used a regular cd). If you get your wallet.dat off cd and use it the virus/malware could have accessed it.
The only way CD or USB data remains safe is if host computer is not infected. If it's infected either one of the ways could possibly lose the file to the security problem.
I agree but atleast it keep the data untouched. A cryptolocker would be fatal on the other hand. Even if they dont get your money, they can make sure that you dont get it either. So thats why everybody should have atleast 2-3 CD backups with a wallet to avoid this disaster. Same could be said is you should have one or two backups of USB sticks. They are not expensive at all (get a decent brand to prevent crapping out). But if you use just one and others are backup if it did get a virus that locked data you could switch computers and usb. USB drives can handle more extreme environment's then CD's in most cases. They also have some that are extra resistant to elements. But I think if computer is compromised CD or USB drive you could be screwed if it's looking for wallet.dat or other files associated with USB. |

Some people discussing about burying the private key in garden. Must be a joke.
Simplest way must be a password protection. The most secure way may be the hardware wallet.
Actually, hiding the private key in the garden is not a bad idea, as long as it's stored correctly. People are crazy about their bitcoins Simplest way to keep bitcoins SAFE is to generate and print a paper wallet offline, or keep the bitcoins on an offline computer. Simplest way to keep SAFE is actually not printing a paper wallet -- it's coming up with your own long pass code. Something like "When I was nine, I fell off my bike on the way home from school" -- things like this are almost guaranteed not to get cracked. And then you need no paper wallet because you just input your code when you need to send funds. On paper wallet I highly suggest if someone uses them to get rid of some of the nicer designs. Just keep what you need (just cut with scissors) don't have bitcoin written all over it as I still don't think standard thief will know bitcoin QR code. Could even put something to mislead them like "Family Pictures" with the QR, etc needed. Chances are they could care less on family pictures if that's what they think it is. Also you could use a usb stick with paper wallet stored on it. Put encryption with passphrase like Ranlo mentioned. He is very right a passphrase is very very hard to a bad guy to brute force compared to password just a LOT more possibilities. |
